The status bar shows a keybinding cheat sheet whenever status_message
is None, but load results like ♪ 118 album(s) were set on screen
load and never cleared, so the help was only visible for a blink before
being overwritten.
Stamp each status message with an Instant and treat entries older than
4s as None at draw time. The 200ms tick loop guarantees the redraw
that flips them back to the help text.
